Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in the attached figure 1, the equipment for manufacturing the double-layer sandwich toast comprises a conveyor 1 for conveying toast, a sandwich supply device 2, a sheet feeding device 3 and a sheet pressing device 4 which are sequentially arranged along the conveying direction of the conveyor 1, and a set of control system (not shown in the figure) which can be a PLC (programmable logic controller) controller and is used for controlling the orderly operation of the conveyor 1, the sandwich supply device 2, the sheet feeding device 3 and the sheet pressing device 4.

As shown in fig. 2 and 3, the sandwich supply device 2 comprises a hopper 21 for containing the sandwich material, a nozzle 22 corresponding to the conveying plane of the conveyor 1 and an extrusion mechanism for extruding the sandwich material onto the conveying plane. The material nozzles 22 are arranged side by side along the width direction of the conveyor 1 and connected to the pipe openings at the bottom of the hopper through pipelines, so that the drainage of the sandwich materials is realized. The extruding mechanism can be a screw extruding and feeding structure in the prior art, and specifically comprises a screw blade 23 vertically connected in the hopper and an output motor 24 fixed at the top of the hopper 21, wherein the screw blade 23 is assembled in the hopper, the lower end of the screw blade 23 is located at a pipe orifice 211 at the bottom of the hopper 21, and the upper end of the screw blade 23 is connected to a conveying shaft of the output motor 24. The output motor 24 operates to drive the helical blade 23 to rotate, so that the sandwich material can be conveyed downwards to the bottom nozzle 211 of the hopper 21, then extruded out to the nozzle 22 through the nozzle 211 at the bottom of the hopper, and finally extruded out to the toast slice 54 on the conveyor 1 through the nozzle 22. Further, the amount of the supplied core material is realized by adjusting the rotation speed of the output motor 24.

As shown in fig. 4 to 8, the sheet feeding device 3 includes a feeding pipe 31, a material cutting plate 33, a material removing plate 32, a rotating shaft 34 and a rotating motor 35. The feeding pipe 31 is fixed on the conveyor 1 by a support frame 36 welded by pipe fittings and is vertical to the conveying plane of the conveyor 1. The feeding pipe 31 has a pipe inner dimension specification which is slightly larger than that of the conventional toast slice, so that the stacked toast slices can be conveniently and vertically fed into the feeding pipe 31, and the stack of toast slices in the feeding pipe 31 can not be inclined. The middle section of the feeding pipe 31 is provided with a material cutting groove 315 and a material removing groove 316 from top to bottom, the feeding pipe 31 comprises an upper pipe 311, a lower pipe 312 and a connecting plate 313 which are sequentially bonded and fixed from top to bottom, the cross section of the connecting plate 313 is bent into a C-shaped structure, two ends of the connecting plate 313 extend along the length of the connecting plate to form a baffle 314, the baffle 314 connected with the rear connecting plate 313 is positioned in a gap between the upper pipe 311 and the lower pipe 312, and gaps are respectively arranged between the baffle 314 and the upper pipe 311 and the lower pipe 312, and the two gaps are the material cutting groove 315 and the material removing groove 316 of the feeding pipe 31. Further, the upper pipe 311, the lower pipe 312 and the connecting plate 313 can be made of transparent acrylic materials, the upper pipe 311, the lower pipe 312 and the connecting plate 313 are fixedly connected through adhesives, and the transparent materials can facilitate observation of the allowance of the stacked toast pieces 51 stacked in the feeding pipe, so that increase is facilitated.

With continued reference to fig. 4 to 8, the planes of the material cutting plate 33 and the material removing plate 32 are both fan-shaped structures, and the planes of the material cutting plate 33 and the material removing plate 32 are both semi-circular structures. The rotating motor 35 is fixed on the support frame 36 and located on the side surface of the feeding pipe 31, the rotating shaft 34 is fixedly connected with an output shaft of the rotating motor 35, the material cutting plate 33 and the material removing plate 32 are sequentially fixed on the rotating shaft 34 from top to bottom, the material cutting plate 33 and the material removing plate 32 are completely staggered, namely gaps formed by fan-shaped planes of the material cutting plate 33 and the material removing plate 32 are completely staggered. In addition, the material cutting plate 33 and the material removing plate 32 are located at the same horizontal position as the material cutting groove 315 and the material removing groove 316, respectively, and when the rotating shaft 34 is driven by the rotating motor 35 to rotate, the material cutting plate 33 and the material removing plate 32 can penetrate through the material cutting groove 315 and the material removing groove 316, respectively.

Before the operation, as shown in fig. 4, the material cutting plate 33 is positioned in the material cutting groove 315 to block the stacked toast slices 51 in the feeding pipe 31, that is, the material cutting plate 33 supports the stacked toast slices 51 stacked in the feeding pipe 31. When the sheet feeding device 3 is operated, the rotating motor 35 drives the rotating shaft 34 to drive the material cutting plate 33 and the material removing plate 32 to rotate, when the material cutting plate 33 gradually rotates to leave the material cutting groove 315, the material removing plate 32 gradually rotates to the material removing groove 316, and when the material cutting plate 33 completely leaves the material cutting groove 315, the rotating body of the material removing plate 32 is completely positioned in the material removing groove 316, as shown in fig. 5, in the process, the stacked toast sheets 51 can fall on the material removing plate 32, that is, the material removing plate 32 supports the stacked toast sheets 51 stacked in the material feeding pipe 31. The rotating motor 35 continues to rotate, when the stripper plate 32 gradually rotates into the stripper groove 316, the first toast slice 52 located on the stripper plate 32 and located upward from the bottom is blocked by the baffle 314 of the connecting plate 313 and cannot move out of the stripper groove 316 along with the stripper plate 32, and at the same time, when the cutter plate 33 gradually rotates to approach the stripper groove 316, as shown in fig. 6 and 7, the cutter plate 33 can cut and separate the toast slice 52 located at the bottom of the stripper plate 32 and the toast slice 53 located above the cutter plate (i.e. the second toast slice located upward from the bottom of the stripper plate) and, because the toast slice 52 located on the top of the stripper plate 32 is blocked by the baffle 314 and cannot move, when the stripper plate 32 completely rotates into the stripper groove 316, the toast slice 52 on the stripper plate 32 smoothly falls onto the conveying plane of the conveyor 1 along the lower pipe 312. By so doing, when the rotating shaft 34 rotates one circle, namely, each circle of the material cutting plate 33 or the material removing plate 32 rotates, one toast piece can fall onto the conveying plane of the conveyor 1 along the feeding pipe and is right above the toast piece 54 in the conveying process of the conveyor.

As shown in fig. 1, 2 and 10, the conveyor 1 may be a belt conveyor in the prior art, and a plurality of isolation rods 12 are equidistantly distributed on the conveyor 1, the distance between each two adjacent isolation rods 12 is slightly larger than the size of a conventional toast piece, and the isolation rods 12 are perpendicular to the conveying direction of the conveyor 1, and the isolation rods 12 are configured to facilitate the discrimination of the front and rear positions of the toast piece placed on the conveyor 1. The conveyor 1 is arranged on a conveying plane and positioned on two sides of the front end of the sandwich supply device 2, and guide plates 11 are further fixed, and the height of each guide plate 11 is higher than that of each isolation rod 12, so that the isolation rods 12 can give way when moving. The two guide plates 11 are flat plates which incline towards the middle of the conveyor 1 from two sides of the conveyor 1, and in the process that the toast piece moves along with the conveyor 1, the structure of the two guide plates 11 can prevent the toast piece from inclining towards two sides of the conveyor 1, and can play a role in correcting the position of the toast piece, so that the toast piece can accurately move in the middle of the conveying plane of the conveyor 1, and the accurate alignment of the subsequent sandwich supply device 2 is convenient for extruding the sandwich and the toast piece 52 is conveniently thrown on the toast piece coated with the sandwich by the piece throwing device 3.

In addition, as shown in fig. 1 and 9, the center of the discharge position of the sandwich supply device 2 is spaced from the center of the discharge position of the sheet throwing device 3 by a multiple of the distance between two adjacent spacer bars 12. Meanwhile, the conveyor 1 can be controlled to operate intermittently by programming in the control system, and the intermittent operation mode is that the moving distance of the conveyor belt of the conveyor 1 is the gap between adjacent separating rods 12, the pause time is the time required by the sandwich supply device 2 to extrude the sandwich to one toast slice 54 on the conveyor 1, or the time required by one toast slice 52 to fall onto the conveyor 1, particularly the longer time. In this way, after the conveyor 1 moves by the displacement amount of the distance between the two spacer bars 12, the sandwich supply device 2 and the tablet throwing device 3 simultaneously perform work of applying the sandwich and throwing the toast tablet 52, and then the conveyor 1 continues to move and stop, and the sandwich supply device 2 and the tablet throwing device 3 continue to perform work of applying the sandwich and throwing the toast tablet on the toast tablet which moves to the lower side next, so that the operation is repeated.

As shown in fig. 9 and 10, the sheeting device 4 includes a conveyor belt 41 and a foot 42 fixed to the bottom of the conveyor belt 41, and the conveyor belt 41 may be a belt type conveyor belt as the conveyor. The supporting legs 42 are fixed on the cross beams on the two sides of the conveyor 1, the gap between the bottom surface of the conveying belt 41 and the conveying plane of the conveyor 1 is slightly smaller than the thickness of the two toast pieces, and the bottom surface of the conveying belt 41 and the conveying plane of the conveyor 1 move in the same direction. The toast pieces 52 thrown by the piece throwing device 3 in the preceding step directly fall on the toast pieces 54 coated with the fillings 55, and the toast pieces 54 are not tightly attached to each other and loosely connected to each other, so that the toast pieces 54 are easily separated and fall off during eating. After the dropped toast piece 52 falls on the toast piece 54 with the sandwiched coating, the toast piece moves with the conveyor 1 to the sheet pressing device 4, and then enters the gap between the bottom surface of the conveyor 41 and the conveying plane of the conveyor 1 with the movement of the conveyor 1 and the conveyor belt 41, so that the toast pieces are pressed by the conveyor belt 41 in the gap. Since the sandwich material extruded from the nozzle 22 of the sandwich feeding device 2 onto the toast slice 54 is extruded from top to bottom, the sandwich 55 is stacked in the toast slice 54 in a conical shape, and the two toast slices can be pressed and flattened into a large-area flat structure to be distributed in the gap between the toast slices in the process of oiling the tabletting device 4, and the two toast slices can be connected more compactly and are not easy to separate due to the relative bonding of the expanded areas of the sandwich 55, and a complete double-layer sandwich toast can be formed.

The specific manufacturing method of the invention is as follows:

the method comprises the following steps: placing a certain amount of toast slices into the feeding pipe 31, so that the toast slices are stacked in the feeding pipe 31 to form a stack of toast slices 51, placing the toast slices 54 on the conveying plane of the conveyor, and placing the toast slices 54 between two adjacent isolation rods 12, which is worth mentioning that in the prior art, the toast slices are made into a multi-slice stacking form when being made, so that when the toast slices are placed in the feeding pipe 31, the multi-slice stacked toast slices can be directly placed at one time, and the toast slices are more convenient and fast;

step two: the toast slice 54 moves to the position right below the center-filling feeding device 2 along with the conveyor 1, and in the moving process, the material nozzle 22 of the center-filling feeding device 2 extrudes the center-filling material to the upper surface of the toast slice 54 so as to finish coating the center-filling 55 of the toast slice 54;

step three: the toast piece 54 continues to move, stops moving to the position below the feeding pipe 31 of the toast throwing device 3, and transfers a toast piece 52 from the toast throwing device 3 to the toast piece 54 which is positioned on the conveyor 1 to coat the sandwich 55, so that the toast piece 54 on the conveyor 1 and the toast piece 54 transferred from the toast throwing device form a structure that two toast pieces are aligned and overlapped;

step four: while the toast slice 52 is lowered by the slice throwing device 3, the centre-filling supplying device 2 applies the centre-filling 55 to the toast slice positioned right below the toast slice;

step five: the two toast slices aligned and overlapped in the third step continue to move to enter the gap between the bottom surface of the conveyer belt 41 of the tabletting device 4 and the conveying plane of the conveyer 1, so that the two toast slices are extruded by the conveyer belt 41 in the gap;

step six: the two toast slices after extrusion are moved out of the tabletting device 4 along with the conveying of the conveyor 1 and the movement of the conveying belt 41, and then complete double-layer sandwich toast can be obtained.

The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
